TO ALL WHOM IT MAY` CONCERN:

Be it known that I, WILLIAM B. TUCKER, of Hillsborough, in the county ofHighland, and State of Ohio, have invented a new and useful Attachmentto the Regulators of Watches and other time-pieces; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings, which form a part ofthis specification- -Figure 1 being a top view of my said attachment,and

Figure 2 a side View ofthe same; the said drawings being of anexaggerated size for the purpose of more clearly representing theinvention. A

Similar letters refer to corresponding parts in each of the drawings.

My Watch-regulator attachment enables the regulator to be moved withcertainty und' accuracy (by means of the watch-key) any desireddistance, however small, a-nd be retained in any desired position,Whatever may be the amount of suddcnness of the movements to which theWatch may be subjected by the movements or occupation of the wearer.

A thin base-plate, a, which has a graduated scale formed upon one sideof it, receives and supports the two knobs b b', which serve as thebearings ofthe horizontal screwshaf`t c. The knob balso receives aspindle descending vertically from the centre ot' the toothed wheel e,which gears into the toothed 1Wheel d on the end of the screw-shaft c.An angular stem,f, rises above the centre of the toothed wheel c,Which'corresponds in size and shape with the angular end of thewinding-arbor of the watch. A nut,'g, which works upon the screwshaft e,is jointed to the extremity of the regulator, (shown by red lines, iig.1,) and a sharp point at the front end ot" said nut indicates upon thesca-le on the base-plate a the exact amount of movement that may beiin'parted to the nut by turning the screw-shaft c, and consequently theamount of movement that may be thereby imparted to theregulator. Thesame key that is employed for winding the watch may be used foradjusting the regulator. The base plate a of my improved watch-regulatorattachment may be secured to the regulatorplate or half-plate in anysuitable manner.

What I claim as my invention, and desire to secure by Letters Patent,is-

Operating the regulator ot' a iva-tch or other time-keeper by means ofan attachment thereto, composed of the scale base-plate a, supportingknobs b Z2', horizontal screw-shaft c, toothed wheels cZ and e,uinding-arborf, and the attaching and indicating nut g, all arranged andoperating substantiallyin the manner herein set forth.

In testimony that' the aforegoing is a true specification of myimprovement in the regulators of watches and other timekcepers, I dohereby sign my name in presence of- W. B. TUCKER.
